                                AMENDED AND RESTATED
                                EMPLOYMENT AGREEMENT


       This AMENDED AND RESTATED EMPLOYMENT AGREEMENT is made and entered into
as of the 30th day of December, 1999 (the "Effective Date"), by and between
Cinergy and Charles J. Winger (the "Executive").  This Agreement replaces and
supersedes any and all prior employment agreements between Cinergy and the
Executive.  The capitalized words and terms used throughout this Agreement are
defined in Section 11.

                                       RECITALS

       A.     The Executive is currently serving as Vice President, Corporate
Development of Cinergy, and Cinergy desires to secure the continued employment
of the Executive in accordance with this Agreement.

       B.     The Executive is willing to continue to remain in the employ of
Cinergy, and any successor to Cinergy, on the terms and conditions set forth in
this Agreement.

       C.     The parties intend that this Agreement will replace and supersede
any and all prior employment agreements between Cinergy (or any component
company or business unit of Cinergy) and the Executive.


                                     AGREEMENT

       In consideration of the mutual premises, covenants and agreements set
forth below, the parties agree as follows:

1.     EMPLOYMENT AND TERM

       a.     Cinergy, and any successor to Cinergy, agree to employ the
              Executive, and the Executive agrees to remain in the employ of
              Cinergy, in accordance with the terms and provisions of this
              Agreement, for the Employment Period set forth in Subsection b.
              The parties agree that the Company will be responsible for
              carrying out all of the premises, covenants, and agreements of
              Cinergy set forth in this Agreement.

       b.     The Employment Period of this Agreement will commence as of the
              Effective Date and continue until December 31, 2002; provided
              that, commencing on December 31, 2000, and on each subsequent
              December 31, the Employment Period will be extended for one (1)
              additional year unless either party gives the other party written
              notice not to extend this Agreement at least ninety (90) days
              before the


<PAGE>

              extension would otherwise become effective.

2.     DUTIES AND POWERS OF EXECUTIVE

              a.     POSITION.  The Executive will serve Cinergy as Vice
              President, Corporate Development of Cinergy, and he will have such
              responsibilities, duties, and authority as are customary for
              someone of that position and such additional duties, consistent
              with his position, as may be assigned to him from time to time
              during the Employment Period by the Board of Directors or the
              Chief Executive Officer.

              b.     PLACE OF PERFORMANCE.  In connection with the Executive's
              employment, the Executive will be based at the principal executive
              offices of Cinergy, 221 East Fourth Street, Cincinnati, Ohio, and,
              except for required business travel to an extent substantially
              consistent with the present business travel obligations of Cinergy
              executives who have positions of authority comparable to that of
              the Executive, the Executive will not be required to relocate to a
              new principal place of business that is more than thirty (30)
              miles from Cinergy's current principal executive offices.

3.     COMPENSATION.  The Executive will receive the following compensation for
       his services under this Agreement.

              a.     SALARY.  The Executive's Annual Base Salary, payable not
              less often than semi-monthly, will be at the annual rate of not
              less than $275,000.00.  The Board of Directors or its designee
              may, from time to time, increase the Annual Base Salary as the
              Board of Directors deems to be necessary or desirable, including
              without limitation adjustments to reflect increases in the cost of
              living. Any increase in the Annual Base Salary will not serve to
              limit or reduce any other obligation of Cinergy under this
              Agreement.  The Annual Base Salary will not be reduced except for
              across-the-board salary reductions similarly affecting all Cinergy
              management personnel.  If Annual Base Salary is increased during
              the Employment Period, then the increased salary will be the
              Annual Base Salary for all purposes under this Agreement.

              b.     RETIREMENT, INCENTIVE, WELFARE BENEFIT PLANS AND OTHER
              BENEFITS. During the Employment Period, the Executive will be
              eligible, and Cinergy will take all necessary action to cause the
              Executive to become eligible, to participate in all short-term and
              long-term incentive, stock option, restricted stock, performance
              unit, savings, retirement and welfare plans, practices, policies
              and programs applicable generally to employees and/or other senior
              executives of Cinergy who are considered Tier II executives for
              compensation purposes, except with respect to any plan, practice,
              policy or program to which the Executive has waived his rights in
              writing.

              If the Executive retires after reaching age 50, the Executive will
              be entitled and fully vested in a supplemental retirement benefit
              equal to the difference between (1) his total benefit under all
              Executive Retirement Plans, and (2) 60% of the Executive's Highest
              Average Earnings times a fraction, the numerator of which is the
              Executive's Years of Participation and the denominator of which is
              35.  If, however, the Executive's employment is terminated
              following a Change in Control, for any reason other than Cause,
              the Executive will be entitled to a supplemental retirement
              benefit equal to the difference between (1) his total benefit
              under all Executive Retirement Plans, and (2) 60% of the
              Executive's Highest Average Earnings. The form, timing, and method
              of payment of the supplemental retirement benefit payable under
              this Paragraph will be the same as those elected by the Executive
              under the Pension Plan.  If the Executive dies after reaching age
              50 but prior to his retirement, and if his Spouse, on the date of
              his death, is living on the date the first installment of the
              supplemental retirement benefit would be payable under this
              Paragraph, the Spouse will be entitled to receive the supplemental
              retirement benefit as a Spouse's benefit.  The form, timing, and
              method of payment of any Spouse's benefit under this Paragraph
              will be the same as those applicable to the Spouse under the
              Pension Plan.

              Upon his retirement on or after having attained age fifty (50),
              the Executive will be eligible for comprehensive medical and
              dental insurance pursuant to the terms of the Retirees' Medical
              Plan and the Retirees' Dental Plan.  The Executive, however, will
              receive the full subsidy provided by Cinergy to retirees for
              purposes of determining the amount of monthly premiums due from
              the Executive.

              The Executive will be a participant in the Annual Incentive Plan,
              and the Executive will be paid pursuant to that plan an annual
              benefit of up to sixty percent (60%) of the Executive's Annual
              Base Salary, with a target of no less than forty percent (40%) of
              the Executive's Annual Base Salary (the "Target Annual Bonus").

              The Executive will be a participant in the Long-Term Incentive
              Plan (the "LTIP"), and the Executive's annualized target award
              opportunity under the LTIP will be equal to no less than seventy
              percent (70%) of his Annual Base Salary (the "Target LTIP Bonus").

              c.     FRINGE BENEFITS AND PERQUISITES.  During the Employment
              Period, the Executive will be entitled to the following additional
              fringe benefits:

              (i)    Cinergy will furnish to the Executive an automobile and
                     will pay all of the related expenses for gasoline,
                     insurance, maintenance, and repairs.


<PAGE>

              (ii)   Cinergy will pay the initiation fee and the annual dues,
                     assessments, and other membership charges of the Executive
                     for membership in a country club selected by the Executive.

              (iii)  Cinergy will provide paid vacation for four (4) weeks per
                     year (or longer if permitted by Cinergy's policy).

              (iv)   Cinergy will furnish to the Executive annual financial
                     planning and tax preparation services.  In addition, the
                     Executive will be entitled to receive such other fringe
                     benefits in accordance with Cinergy plans, practices,
                     programs, and policies in effect from time to time,
                     commensurate with his position and at least comparable to
                     those received by other Cinergy senior executives.

              d.     EXPENSES.  Cinergy agrees to reimburse the Executive for
              all expenses, including those for travel and entertainment,
              properly incurred by him in the performance of his duties under
              this Agreement in accordance with the policies established from
              time to time by the Board of Directors.

              e.     RELOCATION BENEFITS.  Following termination of the
              Executive's employment for any reason (other than death), the
              Executive will be entitled to reimbursement from Cinergy for the
              reasonable costs of relocating from the Cincinnati, Ohio, area to
              a new primary residence in a manner that is consistent with the
              terms of the Relocation Program.

4.     TERMINATION OF EMPLOYMENT

              a.     DEATH.  The Executive's employment will terminate
              automatically upon the Executive's death during the Employment
              Period.

              b.     BY CINERGY FOR CAUSE.  Cinergy may terminate the
              Executive's employment during the Employment Period for Cause.
              For purposes of this Employment Agreement, "Cause" means the
              following:

              (i)    The willful and continued failure by the Executive to
                     substantially perform the Executive's duties with Cinergy
                     (other than any such failure resulting from the Executive's
                     incapacity due to physical or mental illness) after the
                     Board of Directors or the Chief Executive Officer has
                     delivered to the Executive a written demand for substantial
                     performance, which demand specifically identifies the
                     manner in which the Executive has not substantially
                     performed his duties.  This event will constitute Cause
                     even if the Executive issues a Notice of Termination for
                     Good Reason pursuant to Subsection 4d after the Board of
                     Directors or Chief Executive Officer


<PAGE>

                     delivers a written demand for substantial performance.

              (ii)   The breach by the Executive of the confidentiality
                     provisions set forth in Section 9.

              (iii)  The conviction of the Executive for the commission of a
                     felony, including the entry of a guilty or nolo contendere
                     plea, or any willful or grossly negligent action or
                     inaction by the Executive that has a materially adverse
                     effect on Cinergy.  For purposes of this definition of
                     Cause, no act, or failure to act, on the Executive's part
                     will be deemed "willful" unless it is done, or omitted to
                     be done, by the Executive in bad faith and without
                     reasonable belief that the Executive's act, or failure to
                     act, was in the best interest of Cinergy.

       c.     BY CINERGY WITHOUT CAUSE.  Cinergy may, upon at least 30 days
              advance written notice to the Executive, terminate the Executive's
              employment during the Employment Period for a reason other than
              Cause, but the obligations placed upon Cinergy in Section 5 will
              apply.

       d.     BY THE EXECUTIVE FOR GOOD REASON.  The Executive may terminate his
              employment during the Employment Period for Good Reason.  For
              purposes of this Agreement, "Good Reason" means the following:

              (i)    A reduction in the Executive's Annual Base Salary, except
                     for across-the-board salary reductions similarly affecting
                     all Cinergy management personnel, or a reduction in any
                     other benefit or payment described in Section 3 of this
                     Agreement, except for changes to the employee benefits
                     programs affecting all Cinergy management personnel,
                     provided that those changes (either individually or in the
                     aggregate) will not result in a material adverse change
                     with respect to the benefits to which the Executive was
                     entitled as of the Effective Date.

              (ii)   The material reduction without his consent of the
                     Executive's title, authority, duties, or responsibilities
                     from those in effect immediately prior to the reduction or
                     a material adverse change in the Executive's reporting
                     responsibilities.

              (iii)  Any breach by Cinergy of any other material provision of
                     this Agreement (including but not limited to the place of
                     performance as specified in Subsection 2b).

              (iv)   The Executive's disability due to physical or mental
                     illness or injury that precludes the Executive from
                     performing any job for which he is qualified


<PAGE>

                     and able to perform based upon his education, training or
                     experience.

              (v)    A failure by the Company to require any successor entity to
                     the Company specifically to assume all of the Company's
                     obligations to the Executive under this Agreement.

       e.     BY THE EXECUTIVE WITHOUT GOOD REASON.  The Executive may terminate
              his employment without Good Reason upon prior written notice to
              the Company.

       f.     NOTICE OF TERMINATION.  Any termination of the Executive's
              employment by Cinergy or by the Executive during the Employment
              Period (other than a termination due to the Executive's death)
              will be communicated by a written Notice of Termination to the
              other party to this Agreement in accordance with Subsection 12b.
              For purposes of this Agreement, a "Notice of Termination" means a
              written notice that specifies the particular provision of this
              Agreement relied upon and that sets forth in reasonable detail the
              facts and circumstances claimed to provide a basis for terminating
              the Executive's employment under the specified provision.  The
              failure by the Executive or Cinergy to set forth in the Notice of
              Termination any fact or circumstance that contributes to a showing
              of Good Reason or Cause will not waive any right of the Executive
              or Cinergy under this Agreement or preclude the Executive or
              Cinergy from asserting that fact or circumstance in enforcing
              rights under this Agreement.

5.     OBLIGATIONS OF CINERGY UPON TERMINATION.

       a.     CERTAIN TERMINATIONS.

              (i)    If a Termination occurs during the Employment Period,
                     Cinergy will pay to the Executive a lump sum amount, in
                     cash, equal to the sum of the following Accrued
                     Obligations:

                     (1)    the Executive's Annual Base Salary through the Date
                            of Termination to the extent not previously paid;

                     (2)    an amount equal to the AIP Benefit for the fiscal
                            year that includes the Date of Termination
                            multiplied by a fraction, the numerator of which is
                            the number of days from the beginning of that fiscal
                            year to and including the Date of Termination and
                            the denominator of which is three hundred and
                            sixty-five (365).  The AIP Benefit will be
                            determined using a percentage determined by the
                            Chief Executive Officer, in his discretion, up to
                            the maximum percentage specified in Subsection 3b,
                            but no less than the Target Annual Bonus.


<PAGE>

                     (3)    any compensation previously deferred by the
                            Executive (together with any accrued interest or
                            earnings) and any accrued vacation pay, in each case
                            to the extent not previously paid.

                     The Accrued Obligations described in this Paragraph 5a(i)
                     will be paid within thirty (30) days after the Date of
                     Termination.  These Accrued Obligations are payable to the
                     Executive regardless of whether a Change in Control has
                     occurred.

              (ii)   Prior to the occurrence of a Change in Control, and in the
                     event of (A) a Termination other than by reason of the
                     Executive's death, or (B) the Executive's termination of
                     his employment during the Employment Period for Good
                     Reason, Cinergy will pay the Accrued Obligations, and
                     Cinergy will have the following obligations:

                     (1)    Cinergy will pay to the Executive a lump sum amount,
                            in cash, equal to three (3) times the sum of the
                            Annual Base Salary and the AIP Benefit.  For this
                            purpose, the Annual Base Salary will be at the rate
                            in effect at the time Notice of Termination is given
                            (without giving effect to any reduction in Annual
                            Base Salary, if any, prior to the termination).  The
                            AIP Benefit will be determined using a percentage
                            determined by the Chief Executive Officer, in his
                            discretion, which will not be less than the
                            Executive's annual target percentage for the fiscal
                            year in which the Termination occurs and will not be
                            greater than the maximum percentage specified in
                            Subsection 3b.  This lump sum will be paid within
                            thirty (30) days of the Date of Termination.

                     (2)    Cinergy will pay to the Executive the value of all
                            deferred compensation amounts and all executive life
                            insurance benefits whether or not they are otherwise
                            currently vested or payable.  Payment will be made
                            in accordance with the terms of the applicable plan
                            or program.

                     (3)    Except as provided under Clauses (A) and (B) below,
                            Cinergy will continue, until the end of the
                            Employment Period, medical and dental benefits to
                            the Executive and/or the Executive's family at least
                            equal to those that would have been provided if the
                            Executive's employment had not been terminated
                            (excluding benefits to which the Executive has
                            waived his rights in writing).  The benefits
                            described in the preceding sentence will be in
                            accordance with the medical and welfare benefit
                            plans, practices,


<PAGE>

                            programs, or policies of Cinergy (the "M&W Plans")
                            as then currently in effect and applicable generally
                            to other Cinergy senior executives and their
                            families.

                            (A)    If, as of the Executive's Date of
                            Termination, the Executive meets the eligibility
                            requirements for Cinergy's retiree medical and
                            welfare benefit plans, the provision of those
                            retiree medical and welfare benefit plans to the
                            Executive will satisfy Cinergy's obligation under
                            this Subparagraph 5a(ii)(3).

                            (B)    If, as of the Executive's Date of
                            Termination, the provision to the Executive of the
                            M&W Plan benefits described in this Subparagraph
                            5a(ii)(3) would either (1) violate the terms of the
                            M&W Plans or (2) violate any of the Code's
                            nondiscrimination requirements applicable to the M&W
                            Plans, then Cinergy, in its sole discretion, may
                            elect to pay the Executive, in lieu of the M&W Plan
                            benefits described under this Subparagraph
                            5a(ii)(3), a lump sum cash payment equal to the
                            total monthly premiums that would have been paid by
                            Cinergy for the Executive under the M&W Plans from
                            the Date of Termination through the end of the
                            Employment Period.  Nothing in this Clause will
                            affect the Executive's right to elect COBRA
                            continuation coverage under a M&W Plan in accordance
                            with applicable law.

                            (C)    If the Executive becomes employed by another
                            employer and is eligible to receive medical or other
                            welfare benefits under another employer-provided
                            plan, any benefits provided to the Executive under
                            the M&W Plans will be secondary to those provided
                            under the other employer-provided plan during the
                            Executive's applicable period of eligibility.

                     (4)    Ownership of the automobile assigned to the
                            Executive by Cinergy will be transferred to the
                            Executive within 30 days of the Date of Termination.
                            The effect of this transfer will be grossed up for
                            federal and state income taxes as soon as
                            administratively feasible after the transfer is
                            effective.

                     (5)    Cinergy will provide tax counseling services through
                            an agency selected by the Executive, not to exceed
                            Fifteen Thousand Dollars


<PAGE>

                            ($15,000.00) in cost.

              (iii)  In the event of Termination by Cinergy or by the Executive
                     for Good Reason upon or during the twenty-four (24) month
                     period after the occurrence of a Change in Control, then in
                     lieu of any further salary payments to the Executive for
                     periods subsequent to the Date of Termination and in lieu
                     of any other benefits payable pursuant to Paragraph 5a(ii),
                     Cinergy will have the following obligations:

                     (1)    Cinergy will pay to the Executive a lump sum
                            severance payment, in cash, equal to the greater of:

                            (A)    the present value of all amounts and benefits
                                   that would have been due under Paragraph
                                   5a(ii), excluding Subparagraphs 5a(ii)(3),
                                   5a(ii)(4), and 5a(ii)(5), or

                            (B)    three (3) times the sum of (x) the higher of
                                   the Executive's Annual Base Salary in effect
                                   immediately prior to the occurrence of the
                                   event or circumstance upon which the Notice
                                   of Termination is based or in effect
                                   immediately prior to the Change in Control,
                                   and (y) the higher of the amount paid to the
                                   Executive pursuant to all annual incentive
                                   compensation or bonus plans or programs
                                   maintained by Cinergy in the year preceding
                                   that in which the Date of Termination occurs
                                   or in the year preceding that in which the
                                   Change in Control occurs; and

                     (2)    For a thirty-six (36) month period after the Date of
                            Termination, Cinergy will arrange to provide the
                            Executive with life, disability, accident, and
                            health insurance benefits substantially similar to
                            those that the Executive is receiving immediately
                            prior to the Notice of Termination (without giving
                            effect to any reduction in those benefits subsequent
                            to a Change in Control that constitutes Good
                            Reason), except for any benefits that were waived by
                            the Executive in writing.  If Cinergy arranges to
                            provide the Executive with life, disability,
                            accident, and health insurance benefits, those
                            benefits will be reduced to the extent comparable
                            benefits are actually received by or made available
                            to the Executive without cost during the thirty-six
                            (36) month period following the Executive's Date of
                            Termination.  The Executive must report to Cinergy
                            any such benefits that he actually receives.  In
                            lieu of the benefits described in the preceding
                            sentences, Cinergy, in its sole discretion, may
                            elect to pay to the Executive a lump sum cash
                            payment equal to


<PAGE>

                            thirty-six (36) times the monthly premiums that
                            would have been paid by Cinergy to provide those
                            benefits to the Executive.  Nothing in this
                            Subparagraph 5a(iii)(2) will affect the Executive's
                            right to elect COBRA continuation coverage in
                            accordance with applicable law.

                     (3)    Ownership of the automobile assigned to the
                            Executive by Cinergy will be transferred to the
                            Executive within 30 days of the Date of Termination.
                            The effect of this transfer will be grossed up for
                            federal and state income taxes as soon as
                            administratively feasible after the transfer is
                            effective.

                     (4)    Cinergy will provide tax counseling services through
                     an agency selected by the Executive, not to exceed Fifteen
                     Thousand Dollars ($15,000.00) in cost.

                     For purposes of this Paragraph (iii), the Executive will be
                     deemed to have incurred a Termination following a Change in
                     Control if the Executive's employment is terminated prior
                     to a Change in Control, without Cause at the direction of a
                     Person who has entered into an agreement with Cinergy, the
                     consummation of which will constitute a Change in Control,
                     or if the Executive terminates his employment for Good
                     Reason prior to a Change in Control if the circumstances or
                     event that constitutes Good Reason occurs at the direction
                     of such a Person.

       b.     TERMINATION BY CINERGY FOR CAUSE OR BY THE EXECUTIVE OTHER THAN
              FOR GOOD REASON.  Subject to the provisions of Section 7, if the
              Executive's employment is terminated for Cause during the
              Employment Period, or if the Executive terminates employment
              during the Employment Period other than a termination for Good
              Reason, Cinergy will have no further obligations to the Executive
              under this Agreement other than the obligation to pay to the
              Executive the Accrued Obligations, plus any other earned but
              unpaid compensation, in each case to the extent not previously
              paid.

       c.     CERTAIN TAX CONSEQUENCES.

              (i)    In the event that any Severance Benefits paid or payable to
                     the Executive or for his benefit pursuant to the terms of
                     this Agreement or otherwise in connection with, or arising
                     out of, his employment with Cinergy or a change in
                     ownership or effective control of Cinergy or of a
                     substantial portion of its assets (a "Payment" or
                     "Payments") would be subject to any Excise Tax, then the
                     Executive will be entitled to receive an additional payment
                     (a "Gross-Up Payment") in an amount such that after payment
                     by


<PAGE>

                     the Executive of all taxes (including any interest,
                     penalties, additional tax, or similar items imposed with
                     respect thereto and the Excise Tax), including any Excise
                     Tax imposed upon the Gross-Up Payment, the Executive
                     retains an amount of the Gross-Up Payment equal to the
                     Excise Tax imposed upon the Payments.

              (ii)   An initial determination as to whether a Gross-Up Payment
                     is required pursuant to this Agreement and the amount of
                     that Gross-Up Payment will be made at Cinergy's expense by
                     an Accounting Firm selected by the Executive and reasonably
                     acceptable to Cinergy.  The Accounting Firm will provide
                     its determination, together with detailed supporting
                     calculations and documentation, to Cinergy and the
                     Executive within 10 days after the Date of Termination, or
                     such other time as requested by Cinergy or by the
                     Executive, and if the Accounting Firm determines that no
                     Excise Tax is payable by the Executive with respect to a
                     Payment or Payments, it will furnish the Executive with an
                     opinion reasonably acceptable to the Executive that no
                     Excise Tax will be imposed with respect to any such Payment
                     or Payments.  Within 10 days after the Accounting Firm
                     delivers its determination to the Executive, the Executive
                     will have the right to dispute the determination.  The
                     Gross-Up Payment, if any, as determined pursuant to this
                     Subsection 5c will be paid by Cinergy to the Executive
                     within five days of the receipt of the Accounting Firm's
                     determination.  The existence of a dispute will not in any
                     way affect the Executive's right to receive the Gross-Up
                     Payment in accordance with the determination.  If there is
                     no dispute, the determination will be binding, final, and
                     conclusive upon Cinergy and the Executive.  If there is a
                     dispute, then Cinergy and the Executive will together
                     select a second Accounting Firm, which will review the
                     determination and the Executive's basis for the dispute and
                     then will render its own determination, which will be
                     binding, final, and conclusive on Cinergy and on the
                     Executive.  Cinergy will bear all costs associated with
                     that determination, unless the determination is not greater
                     than the initial determination, in which case all such
                     costs will be borne by the Executive.

              (iii)  The value of any non-cash benefits or any deferred payment
                     or benefit paid or payable to the Executive will be
                     determined in accordance with the principles of Code
                     paragraphs 280G(d)(3) and (4).  For purposes of determining
                     the amount of the Gross-Up Payment, the Executive will be
                     deemed to pay federal income taxes at the highest marginal
                     rate of federal income taxation in the calendar year in
                     which the Gross-Up Payment is to be made and applicable
                     state and local income taxes at the highest marginal rate
                     of taxation in the state and locality of the Executive's
                     residence on the Date of Termination, net of the maximum
                     reduction in


<PAGE>

                     federal income taxes that would be obtained from deduction
                     of those state and local taxes.

              (iv)   Notwithstanding anything contained in this Agreement to the
                     contrary, in the event that, according to the Accounting
                     Firm's determination, an Excise Tax will be imposed on any
                     Payment or Payments, Cinergy will pay to the applicable
                     government taxing authorities as Excise Tax withholding,
                     the amount of the Excise Tax that Cinergy has actually
                     withheld from the Payment or Payments in accordance with
                     law.



              d.     VALUE CREATION PLAN AND STOCK OPTIONS.  Upon the
              Executive's termination of employment for any reason, the
              Executive's entitlement to restricted shares and performance
              shares under the Value Creation Plan and any stock options
              granted under the Stock Option Plan or the LTIP will be
              determined under the terms of the appropriate plan and any
              applicable administrative guidelines and written agreements.

              e.     OTHER FEES AND EXPENSES.  Cinergy will also pay to the
              Executive all legal fees and expenses incurred by the Executive in
              successfully disputing a Termination that entitles the Executive
              to Severance Benefits.  Payment will be made within five (5)
              business days after delivery of the Executive's written request
              for payment accompanied by such evidence of fees and expenses
              incurred as Cinergy reasonably may require.

6.     NON-EXCLUSIVITY OF RIGHTS.  Nothing in this Agreement will prevent or
       limit the Executive's continuing or future participation in any benefit,
       plan, program, policy, or practice provided by Cinergy and for which the
       Executive may qualify, except with respect to any benefit to which the
       Executive has waived his rights in writing or any plan, program, policy,
       or practice that expressly excludes the Executive from participation.  In
       addition, nothing in this Agreement will limit or otherwise affect the
       rights the Executive may have under any other contract or agreement with
       Cinergy entered into after the Effective Date.  Amounts that are vested
       benefits or that the Executive is otherwise entitled to receive under any
       benefit, plan, program, policy, or practice of, or any contract or
       agreement entered into after the Effective Date with Cinergy, at or
       subsequent to the Date of Termination, will be payable in accordance with
       that benefit, plan, program, policy or practice, or that contract or
       agreement, except as explicitly modified by this Agreement.

7.     FULL SETTLEMENT:  MITIGATION.  Cinergy's obligation to make the payments
       provided for in this Agreement and otherwise to perform its obligations
       under this Agreement will not be affected by any set-off, counterclaim,
       recoupment, defense, or other claim, right, or action that Cinergy may
       have against the Executive or others.  In no event will the Executive be


<PAGE>

       obligated to seek other employment or take any other action by way of
       mitigation of the amounts (including amounts for damages for breach)
       payable to the Executive under any of the provisions of this Agreement
       and, except as provided in Subparagraphs 5a(ii)(3) and 5a(iii)(2), those
       amounts will not be reduced simply because the Executive obtains other
       employment.  If the Executive finally prevails on the substantial claims
       brought with respect to any dispute between Cinergy and the Executive as
       to the interpretation, terms, validity, or enforceability of (including
       any dispute about the amount of any payment pursuant to) this Agreement,
       Cinergy agrees to pay all reasonable legal fees and expenses that the
       Executive may reasonably incur as a result of that dispute.

8.     ARBITRATION.  The parties agree that any dispute, claim, or controversy
       based on common law, equity, or any federal, state, or local statute,
       ordinance, or regulation (other than workers' compensation claims)
       arising out of or relating in any way to the Executive's employment, the
       terms, benefits, and conditions of employment, or concerning this
       Agreement or its termination and any resulting termination of employment,
       including whether such a dispute is arbitrable, shall be settled by
       arbitration.  This agreement to arbitrate includes but is not limited to
       all claims for any form of illegal discrimination, improper or unfair
       treatment or dismissal, and all tort claims.  The Executive will still
       have a right to file a discrimination charge with a federal or state
       agency, but the final resolution of any discrimination claim will be
       submitted to arbitration instead of a court or jury.  The arbitration
       proceeding will be conducted under the employment dispute resolution
       arbitration rules of the American Arbitration Association in effect at
       the time a demand for arbitration under the rules is made.  The decision
       of the arbitrator(s), including determination of the amount of any
       damages suffered, will be exclusive, final, and binding on all parties,
       their heirs, executors, administrators, successors and assigns.  Each
       party will bear its own expenses in the arbitration for arbitrators' fees
       and attorneys' fees, for its witnesses, and for other expenses of
       presenting its case.  Other arbitration costs, including administrative
       fees and fees for records or transcripts, will be borne equally by the
       parties.  Notwithstanding anything in this Section to the contrary, if
       the Executive prevails with respect to any dispute submitted to
       arbitration under this Section, Cinergy will reimburse or pay all legal
       fees and expenses that the Executive may reasonably incur as a result of
       the dispute as required by Section 7.

9.     CONFIDENTIAL INFORMATION.  The Executive will hold in a fiduciary
       capacity for the benefit of Cinergy, as well as all of Cinergy's
       successors and assigns, all secret, confidential information, knowledge,
       or data relating to Cinergy, and its affiliated businesses, that the
       Executive obtains during the Executive's employment by Cinergy or any of
       its affiliated companies, and that has not been or subsequently becomes
       public knowledge (other than by acts by the Executive or representatives
       of the Executive in violation of this Agreement).  During the Employment
       Period and thereafter, the Executive will not, without Cinergy's prior
       written consent or as may otherwise by required by law or legal process,
       communicate or divulge any such information, knowledge, or data to anyone
       other than Cinergy and those designated by it.  The


<PAGE>

       Executive understands that during the Employment Period, Cinergy may be
       required from time to time to make public disclosure of the terms or
       existence of the Executive's employment relationship to comply with
       various laws and legal requirements.  In addition to all other remedies
       available to Cinergy in law and equity, this Agreement is subject to
       termination by Cinergy for Cause under Section 4b in the event the
       Executive violates any provision of this Section.

10.    SUCCESSORS.

       a.     This Agreement is personal to the Executive and, without Cinergy's
              prior written consent, cannot be assigned by the Executive
              otherwise than by will or the laws of descent and distribution.
              This Agreement will inure to the benefit of and be enforceable by
              the Executive's legal representatives.

       b.     This Agreement will inure to the benefit of and be binding upon
              Cinergy and its successors and assigns.

       c.     Cinergy will require any successor (whether direct or indirect, by
              purchase, merger, consolidation or otherwise) to all or
              substantially all of the business and/or assets of Cinergy to
              assume expressly and agree to perform this Agreement in the same
              manner and to the same extent that Cinergy would be required to
              perform it if no succession had taken place.  Cinergy's failure to
              obtain such an assumption and agreement prior to the effective
              date of a succession will be a breach of this Agreement and will
              entitle the Executive to compensation from Cinergy in the same
              amount and on the same terms as if the Executive were to terminate
              his employment for Good Reason after a Change in Control, except
              that, for purposes of implementing the foregoing, the date on
              which any such succession becomes effective will be deemed the
              Date of Termination.

              Attn: Chief Executive Officer

              or to such other address as either party has furnished to the
              other in writing in accordance with this Agreement.  All notices
              and communications will be effective when actually received by the
              addressee.

       c.     The invalidity or unenforceability of any provision of this
              Agreement will not affect the validity or enforceability of any
              other provision of this Agreement.

       d.     Cinergy may withhold from any amounts payable under this Agreement
              such federal, state, or local taxes as are required to be withheld
              pursuant to any applicable law or regulation.

       e.     The Executive's or Cinergy's failure to insist upon strict
              compliance with any provision of this Agreement or the failure to
              assert any right the Executive or Cinergy may have under this
              Agreement, including without limitation the right of the Executive
              to terminate employment for Good Reason pursuant to Subsection 4c
              or the right of Cinergy to terminate the Executive's employment
              for Cause pursuant to Subsection 4b, will not be deemed to be a
              waiver of that provision or right or any other provision or right
              of this Agreement.

       f.     This instrument contains the entire agreement of the Executive and
              Cinergy with respect to the subject matter of this Agreement; and
              subject to any agreements evidencing stock option or restricted
              stock grants described in Subsection 3b and the Stock Related
              Documents, all promises, representations, understandings,
              arrangements, and prior agreements are merged into this Agreement
              and accordingly superseded.

       g.     This Agreement may be executed in counterparts, each of which will
              be deemed to be an original but all of which together will
              constitute one and the same instrument.
